[STR New] Link: http://www.fltk.org/str.php?L2941 Version: 1.3-feature @Ian, can't blame you -- impressed you took on fl_text_extents() at all.. big job, multiple platforms! But isn't the multiline issue simpler? Perhaps I'm missing something, but I would think the hard work has been done already.. The case of multiple lines, a three line example might be: First line Middle line Last line Forgetting alignment for now, and assuming first and last lines aren't blank (can be determined with fl_text_extent() to see if there's no inking area) and we want the dx/dy/w/h extents of this multiline string, wouldn't the overall 'h' of all three lines be the sum of FH+MH+LH, where: FH = fl_height()-dy of "First line" MH = fl_height() LH = dy of "Last line" e.g: _____________________ _____ dy | ###### # ##### #### ##### | | # # # # # # | | ##### # # # #### # | FH | fl_height() # # ##### # # | | # # # # # # # | | # # # # #### # | | . <-- baseline __|_______________|__ | | # # # #### #### # #### | | ## ## # # # # # # # | | # ## # # # # # # # ### | MH | fl_height()) # # # # # # # # # | | # # # # # # # # # | | # # # #### #### #### #### | | . <-- baseline |_______________|__ | | # ## #### ##### | | # # # # # | LH | # # # #### # | (dy of last) | fl_height() # ###### # # | | # # # # # # | | ###### # # #### # __|___ | . <-- baseline __________________|__ And this would of course extend to any number of middle lines. The trick would be to watch out for leading and trailing blank lines, but these could be detected by the existing fl_text_extent() on each line to detect the first and last inked lines, and adjust dy and h. What I figure gets tricky is the mixture of the FL_ALIGN_* flags which affect horiz + vertical orientation (INSIDE, OUTSIDE) as well as the origin of each line (CENTER). Tabs might be another issue, not sure. But I guess all this nothing the multiline fl_draw() doesn't already do to calculate text alignment, and you've already done the hard work to calculate font inking sizes.
